Abstract: A mobile-controlled electric entrance device includes an electrically powered entrance body and a control unit. The control unit includes a mobile phone number comparison unit, a storage unit, an oscillation timer, a delay and sequential logical decoding unit, a current driver and a relay switch. The mobile phone number comparison unit receives a call from the mobile phone with a phone number and demodulates the number to be compared with a plurality of predetermined phone numbers. If the phone number is not found in the predetermined phone numbers, the mobile phone number comparison unit is back to a stand-by state. If the phone number is found in the predetermined phone numbers, the mobile phone number comparison unit transmits a signal to trigger the oscillation timer to generate a sequential pulse for opening or closing the electrically powered entrance body.
